Further, the controller 8 checks data inputted through a selectively-provided key input unit 16 against predetermined data taken out from the extractor 7.

TECHNICAL FIELD

The present invention relates to a multibroadcast receiver with a card,and to a multibroadcast receiving system capable of more effectivelyutilizing a radio massmedia system with a card as a medium between theaudience side and the broadcasting station side.

BACKGROUND ART

A radio massmedia system using a normal broadcast receiver such as atelevision, a radio or the like basically provides information through aunilateral or unidirectional communication made from a broadcastingstation or a program sponsor (hereinafter called "broadcasting stationside") to an audience/listener (hereinafter called "audience side"). Itis necessary for the broadcasting station side to continue to sendinformation to many and unspecified persons or parties at all timeswhile whether or not the viewers are watching and listening in fact,remains unknown. Further, the audience side must select necessaryinformation from random and massive amounts of information given bybroadcasting. Therefore, the degree of information transfer to theaudience side can be actually said low. The broadcasting station siderepeatedly sends increasingly massive amounts of information to theaudience side to overcome the low degree of information transfer,thereby causing a vicious circle that a further increase in labors ortrouble occurs to select information. Thus, the broadcasting stationside incurs a result that even when the amount of information to begiven is increased, commercial effects which are commensurate with thatcannot be achieved.

A broadcast for transmitting a digital data signal using amultibroadcasting radio wave or PCM broadcasting radio wave used for atelevision and a radio has been recently put to practical use. This typeof broadcast is of a system capable of simultaneously transmittingadditive information based on the digital data signal together with ageneral broadcasting program and has a potential that a problemdeveloped due to the unidirection of the aforementioned informationtransfer can be reduced by using such additive information.

The present invention has been made from the foregoing points of view,and it is an object of the present invention to solve the aforementionedproblems developed in radio mass media, i.e., the increase in troubleincident to the selection of information and the decrease in commercialeffects due to the reduction in the degree of information transfer byeffectively utilizing a multibroadcasting system.

DISCLOSURE OF THE INVENTION

In order to achieve the above object, the present invention provides amultibroadcast receiver for including an identification code related tothe contents of a broadcasting program in a data signal carried by anadditive-information radio wave in a multibroadcasting radio wave andextracting information desired by an audience from the data signal,based on the identification code, comprising:

means for extracting the identification code related to the contents ofthe broadcasting program from the data signal;

a portion for inserting therethrough a card with a predeterminedidentification code recorded thereon;

means for reading the identification code from the card inserted intothe insert portion;

recording means for writing necessary information included in the datasignal into the inserted card; and

control means for checking the identification code extracted from thedata signal against the identification code read from the card andcontrolling the recording means in accordance with the check result.

Further, the present invention provides a broadcast receiving systemcomprising:

a broadcasting station for including an identification code related tothe contents of a broadcasting program in a data signal carried by anadditive-information radio wave in a multibroadcasting radio wave andbroadcasting the same;

a card having the identification code recorded thereon in advance;

a multibroadcast receiver having an insert portion for inserting thecard therethrough and constructed so that information necessary toidentify the contents of the broadcasting program is extracted from thedata signal, based on the identification code recorded on the card andis recorded on the card; and

card recovery locations scattered within a broadcasting area so as torecover the card;

whereby high value-added information or physical services such as apremium, present, etc. are provided at the card recovery locations basedon the records on the card, while the records on the card which arecollected through the card recovery locations are used for statisticalprocessing.

The multibroadcast receiver and multibroadcast receiving system can beused as described below and can reduce labors made when the audienceside selects information, according to the way of using them.

A card on which an identification code corresponding to "Artist name",for example, is recorded is inserted into the insert portion of themultibroadcast receiver. When the card is inserted into the insertportion, the reading means reads the identification code from the card.The extracting means of the multibroadcast receiver takes out theidentification code (which is transmitted so as to be included in abroadcasting radio wave as a data signal in unison with a piece of musicbeing on air by a broadcasting station) corresponding to the artist namefrom the data signal in the multibroadcasting radio wave. The controlmeans checks the identification code read from the card against theidentification code taken out of the data signal in the radio wave. Whenthe identification codes coincide with each other, the usage of themultibroadcast receiver and the multibroadcast receiving system is madepossible that, for example, information (e.g., entertainment informationabout a singer, words of a song, etc.) about music being on air at thattime from the data signal carried by the additive-information radio wavealong with the identification code of the artist name is recorded on thecard inserted into the insert portion (as an alternative to therecording of the information on the card, a character code sent as adata signal may be printed in the form of characters or magneticallyrecorded).

Similarly, a card having a predetermined identification code obtained bycombining a "traffic information program code" and a "by-geographicarea/by-route code" together is inserted into the insert portion. Atraffic information program included in the data signal in themultibroadcasting radio wave is checked against an identification coderelated to a by-geographic area/route to thereby limitatively receivetraffic information about a predetermined area only. As a result, thereceived traffic information can be recorded on the card. When theaudience is scheduled to buy certain merchandise, a card having anidentification code related to the merchandise, e.g., "merchandisecommercial classification code" is inserted into the insert portion. Theabove"merchandise commercial classification code" is included in thedata signal in the multibroadcast radio wave so as to correspond to abroadcasted commercial. Similarly to the above, the identification codetaken out by the extracting means is checked against the identificationcode read by the reading means. When they coincide with each other, theusage of the multibroadcast receiver and the multibroadcast receivingsystem is made possible that, for example, detailed information aboutthe usage, price and selling locations of merchandise advertised at thattime from the data signal carried by the additive-information radio wavealong with the "merchandise commercial classification code", is recordedon the card.

Namely, when they are used in this way, the audience can automaticallytake out his/her desired information from random and massive amounts ofinformation by simply selecting a card having an identification codethat satisfies his/her own desire and inserting it into themultibroadcast receiver. It is therefore possible to save labors orefforts required to select the information. Since the taken-outinformation is recorded on the card, the audience can carry theinformation and re-use it whenever they like.

On the other hand, if a predetermined identification code fit for thepurpose of the broadcasting station side is recorded on a card and thecard is distributed to the audience side, then the broadcasting stationside can substantially broadcast to a limited audience. One example willbe described. A program or advertisement sponsor distributes cards eachhaving an identification code corresponding to its own company, e.g., a"sponsor code" recorded thereon, to the audience side in advance. Thesponsor ties up with the broadcasting station so that the "sponsor code"is broadcasted simultaneously with a program or commercial thereof withthe "sponsor code" included in a data signal. Thus, the multibroadcastreceiver and the multibroadcast receiving system can provide the usagethat when both identification codes coincide with each other in the samemanner as described above, the sponsor provides only the audience havingthe cards with advantageous information such as new-product information,a discount price, the term of a discount sale, etc. Namely, thebroadcasting station side can restrict suitable commercials only topersons who often watch the program or commercial for the sponsor or topersons who use the sponsor's goods habitually.

Similarly, for example, such contents as a man in his twenties whosehobby is skiing are coded and recorded on a card as a "age/sex/hobbylimitation code". The broadcasting station side distributes the card tothe audience side in advance. Thus, the multibroadcast receiver and themultibroadcast receiving system can provide the usage that, for example,a company for selling ski goods cooperates with a broadcasting stationso that the broadcasting station broadcasts a commercial about the skigoods along with a data signal including the above identification codetherein. Namely, since the company can advertise the ski goods intendedfor only persons who consider skis as hobbies, a higher commercialeffect can be expected.

Further, cards having a "XX fan-club membership code" and a "XX companystaff code" recorded thereon as identification codes are distributed tomembers of a fan club or staffs of a special enterprise in advance.Thereafter, detailed information is recorded on the corresponding cardthrough the multibroadcast receiver in which the card having theidentification codes has been inserted. In some cases, the reception andreproduction of a general broadcast can be controllably constituted.Thus, the broadcasting station side can substantially realize a privatebroadcast.

In using the multibroadcast receiver according to the present invention,the broadcasting station side may tie up with a number of conveniencestores in a broadcasting area so as to provide card recovery locations.Namely, a file server is disposed in each card recovery location so thatinformation unable to be directly recorded or recorded on a card issecondarily recorded or printed out on the card by using the fileserver.

Namely, for example, a "pamphlet desired code", a "by-geographicarea/by-route code", etc., each of which indicates an output instructionmade to the server, are set so as to be included in a data signalcarried by an additive-information radio wave in a multibroadcast radiowave. When a certain program or commercial is received based on apredetermined identification code recorded on a card and necessaryinformation is taken out from the data signal so as to be recorded onthe card again, the aforementioned "pamphlet desired code" and"by-geographic area/by-route code" are also recorded on the same cardalong with the necessary information. Next, the audience brings the cardto its corresponding card recovery location where the "pamphlet desiredcode" and "by-geographic area/by-route code" are read by a suitablereader. Thereafter, a merchandise pamphlet and a road map displayed withcolor images, for example, are outputted from the corresponding fileserver.

Thus, the card on which the identification code related to thebroadcasting program is recorded from the data signal in themultibroadcast radio wave by the multibroadcast receiver, can beregarded as evidence (audiovisual certification) that the audience wasreally watching or listening to a broadcasting program. Thus, if thecard is recovered by a suitable method such as mailing or the like andthe contents recorded on the card are confirmed at the card recoverylocation, then high value-added information, e.g., valuable physicalservice such as a premium, a sample, a benefit, a square piece of fancypaper, a concert ticket, etc. can be easily offered only to the personswho was really watching or listening to the broadcasting program.

Namely, when a certain sponsor invites an application to the audiencefor providing the audience with a sample or present during abroadcasting program, the sponsor cannot exclude persons who do notreally watch or listen to the program from making applications or oneperson from making a plurality of applications. However, the sponsor canstrictly select one of applicants by using a card as an audiovisualcertification.

Another advantage of the card that serves as the audiovisualcertification is that various data recorded on the card can be used foran audience trend survey (such as an audience rating of a program,seizing of distribution of an audience age group, an audience preferencesurvey or the like).

The following usage is also made possible if an external inputting meansis further added to the above multibroadcast receiver and the controlmeans performs control for checking data input from the externalinputting means against predetermined data included in a received datasignal and recording necessary information taken out of the data signalon a card in accordance with the result of check.

Namely, for example, a broadcasting station provides quizzes through abroadcasting program for a radio or television and sends a correctanswer to the each quiz through a data signal. Thus, the usage is madepossible that the audience checks his answer input through the externalinputting means against the correct answer to the quiz and the result ofcheck is recorded on a card for display.

In doing so, various uses that, for example, the audience can recognizea correctness or incorrectness relative to the answer to the set quizsubstantially in real time and the audience can bring the card to thecard recovery location to receive the premium, can be realized, therebymaking possible to provide a very interesting broadcasting programcapable of arousing the interest of the audience.

Further, the following usage is also made possible, if a writeinstruction signal and a read instruction signal for the recording meansand the reading means are included in a data signal carried by anadditive-information radio wave sent from a broadcasting station; andthe control means controls the recording means and the reading means inaccordance with the write and read instruction signals to perform thereading and writing of information from and into a card.

Namely, after a quiz has been set through a broadcasting program, thebroadcasting station sends the write instruction signal after the elapseof a predetermined time interval so that the multibroadcast receivertemporarily records an audience answer issued from the externalinputting means on the card. Next, the broadcasting station sends acorrect answer to the quiz and transmits the read instruction signal toallow the reading means to read the audience answer so as to be checkedagainst the above correct answer.

In doing so, the broadcasting station side can actively restrict thetime (answer reception time) between setting and answering the quiz.Thus, the broadcasting station side can provide a quiz program at quicktempo in unison with the program progress. Further, after an audienceanswer issued from the external inputting means has been temporarilyrecorded on a card by a certain multibroadcast receiver, the audiencebrings the card to other multibroadcast receiver where the correctnessor incorrectness relative to the answer to the quiz can be confirmed.Thus, the usage is made possible that the audience makes an answer to aquiz at his/her own house in the morning and the correctness orincorrectness relative to its answer is confirmed at the workplace inthe noon recess.

The above usage can be applied to the guess of the issue about matchessuch as baseball, basket, soccer, etc., replies submitted to aquestionnaire and applications for a premium, a ticket, various samples,a benefit, etc., as well as to the setting of quizzes. Alternatively,the usage can be applied to an audience entry-type game by suitablyvarying the contents of a message printed on a card based on data givenfrom an external inputting means. Further, various uses such as aradio"television shopping program, an educational program, etc. can beconsidered.

The following are considered as the recording of the information on thecard according to the above usage. Namely, the information ismagnetically or electrically recorded on a pet card or an IC card.Alternatively, the information is printed out onto a card such as paperby using a callular code, a bar code or characters. The former isdesirable in that the information storage capacity per unit area of thecard can be made great, whereas the latter is desirable in that themanufacturing cost of the card is cheap and the contents recorded on thecard are visible to the naked eye.

BEST MODE FOR CARRYING OUT THE INVENTION

First embodiment!

A first embodiment according to the present invention will be describedwith reference to FIGS. 1 through 5. As shown in FIGS. 1 and 2, amultibroadcast receiver 1 according to the present invention comprises astereo receiving unit 4, an extractor 7, a controller 8, a display 9, aprint unit 10, an insert portion 12 for inserting a card 11therethrough, a reader 13 and an unillustrated memory.

The stereo receiving unit 4 receives a broadcasting wave by an FM tuner2 and outputs sound or voices from a speaker through an audio amplifier3. The extractor 7 takes out necessary data included in a binary datasignal carried by an additive-information radio wave in themultibroadcasting wave. The extractor 7 comprises an L-MSK demodulator 5(Level Controlled Minimum Shift Keying; digital modulation system forvarying a multilevel according to a modulation factor of a stereodifference signal) and an error correcting decoder 6. The controller 8processes an identification code related to the contents of abroadcasting program extracted from the extractor 7, various controlsignals and signals inputted from other peripheral devices, convertsthem into predetermined character codes or control codes and performsnecessary various controls on peripheral devices. The display 9 uses aliquid crystal display element and suitably displays necessaryinformation under the control of the controller 8. The print unit 10 iscomposed of a thermal printer and receives necessary data from thecontroller 8 so as to print it on the card 11 inserted into the insertportion 12. The insert portion 12 is used to insert the card 11 to bedescribed later therethrough and is selectively provided with a sensorfor detecting whether the card 11 exists. The reader 13 is composed ofan optical reader, which reads an identification code on the card 11 inthe insert portion 12 and sends it to the controller 8.

As shown in FIG. 3, the card 11 is shaped in the form of a thinplate-like card printable by the print unit 10. A hexadecimal 4-digitcaller code 14 is printed on an upper stage of the card 11 as anidentification code. The caller code 14 is read when inserted into theinsert portion 12 and is stored in an unillustrated memory by thecontroller 8. Further, a recording space S for printout of the printunit 10 is provided at a lower stage of the card 11. The recording spaceS is of a recording space for printing characters (such as a programname, a quiz name, the data and hour of a broadcast) related to thecontents of a program taken out of a data signal in the broadcastingwave and caller codes 15 indicated by coded identification codes, suchas instructions for outputting words relative to a file server locatedin a card recovery location, etc.

Although not shown in FIG. 3 nor 4, a postcard form or format having aspace for entering an address and characters is printed on the reverseside of the card 11 so as to facilitate mailing the card from anaudience to a broadcasting station or vice versa. The size of the card11 is set to the order of that of the postcard as shown in FIG. 5. Aboutthe half of the card 11 is inserted into the insert portion 12, whereasthe other half may be used as a space for entering characters or anadvertisement space for a sponsor.

Incidentally, the caller codes 14 and 15 may be printed on the card 11by magnetic ink or special ink so as to prevent unauthorized usage ofthe card 11. The caller codes 14 and 15 are illustrated as the 4-digitcodes. However, they are suitably set as 5-digit or more codes accordingto the magnitude of an audible broadcasting area, the number of audienceor the quantity of information to be included.

The way of using the multibroadcast receiver 1 will now be described. Anidentification code corresponding to a certain specific singer isprinted on the card 11 as the caller code 14 in advance.

When the card 11 is inserted into the insert portion 12 in a state inwhich a power switch (not shown) is being turned ON, the reader 13located in the position corresponding to the card 11 reads the callercode 14 and sends the result of reading to the controller 8. Thecontroller 8 converts the input into checkable identification data byreferring to a conversion table and the identification data is suitablystored in the memory.

The extractor 7 takes out an identification code related to the contentsof a broadcasting program included as header information indicative of adata signal in the multibroadcasting wave and sends it to the controller8. The controller 8 checks the identification code supplied from theextractor 7 against the identification code stored in the memory. Whenthey coincide with each other (they may be made inconsistent with eachother according to the condition), the controller 8 receivespredetermined data in a general-purpose data area, which is sentsubsequently to the header, from the extractor 7 and causes the printunit 10 to print the data within the recording space S on the card 11 inthe form of the characters and the caller code 15.

Thus, when the card 11 is set in the insert portion 12 of themultibroadcast receiver 1, the audience can automatically printnecessary data on the card 11 when a piece of music sung by a specificsinger is played on air. Further, the audience refers to the card 11 atthe card recovery location as needed and acquires entertainmentinformation about the specific singer or words from the file serverbased on the caller code 15. In the illustrated embodiment, the contentsrecorded on the card 11 include characters for identifying a program andinstructions for outputting words to the file server. However, charactercodes indicative of words may be included in the general-purpose dataarea so that the words are directly set out on the card 11.

The data signal employed in the present embodiment is constructed with abit string composed of, for example, 16 Kbps as one group and includesidentification codes related to the contents of a broadcasting program,numerical data, text data, graphic-element (mosaic set for map drawing)data, other additive information, and the like are included in aninformation word area of 6.83 Kbps excluding a check word area of 9.17Kbps. The data signal is multiplexed at the broadcasting station so asto be transmitted synchronously with the progression of a normalbroadcasting program.

Second embodiment!

A second embodiment will now be described with reference to FIGS. 6through 10. As is understood from FIGS. 6 and 7, a key input unit 16used as an external inputting means is added to the second embodiment inaddition to the structure of the first embodiment. In the figure, thekey input unit 16 is directly mounted on the upper surface of amultibroadcast receiver 1. However, the key input unit 16 may beconnected to a controller 8 so as to be able to perform remote controlusing infrared rays, a weak radio wave, etc. Incidentally, a memory M issimply shown in the second embodiment although not shown in the firstembodiment.

As shown in FIGS. 8 and 9, a card 17 is basically identical to the card11 employed in the first embodiment. A caller code 18 equivalent to thecaller code 14 employed in the first embodiment is recorded on an upperstage of the card 17. A recording space (not shown) for printing of aprint unit 10 is provided at a lower stage of the card 17 in the samemanner as the first embodiment. When the card 17 is inserted into aninsert portion 12, caller codes 19 corresponding to the caller codes 15employed in the first embodiment are printed on the recording space. Thecaller codes 19 include data input from the key input unit 16 as will bedescribed later. A caller code 20 provided at the lowest stage of therecording space will be described later.

One example of the way of using the second embodiment will now bedescribed with reference to FIG. 10. A program identification code foridentifying a broadcasting program called "XX quiz" is printed on thecard 17 in advance as the caller code 18. When the card 17 is firstinserted into the insert portion 12 in an ON state of a power switch asthe preceding stage, a reader 13 located in a position corresponding tothe card 17 reads the caller code 18 and sends the result of reading tothe controller 8. The controller 8 converts the read information intocheckable identification data by using a conversion table or the likeand allows the converted data to be stored in the memory M. Further, thecontroller 8 recognizes that the data is of identification data for aquiz program and enters into an external input reception mode.

An extractor 7 takes out a program identification code (corresponding tothe identification code associated with the "XX quiz" in the presentembodiment) related to the contents of a broadcasting program includedas a header for a data signal in a multibroadcasting wave and sends itto the controller 8. The controller 8 checks the identification codetaken out from the extractor 7 against the identification code stored inthe memory M. When they coincide with each other, the controller 8suitably performs receiver control (setup) such as an increase in volumeor sound level and is thereafter brought into an input standby state S1.

The proceeding of the controller 8 to the input standby state S1 can beexecuted by various methods. The controller 8 may be manually shifted tothe input standby state S1 by an additionally-provided switch, forexample. Alternatively, the controller 8 may be automatically shifted tothe input standby state S1 simultaneously with the turning ON of thepower. Further, an instruction signal for a shift to an external inputreception mode is included in predetermined data within thegeneral-purpose data area, which is sent subsequently to the header.When the shift instruction signal is taken out through the extractor 7subsequently to the header in this state, the controller 8 may be causedto control the shift to the input standby state.

Next, when the controller 8 is in the input standby state S1, forexample, a quiz is set during a broadcasting program and an audience isurged to answer by numbers using the key input unit 16 (S2). When, forexample, "3" in the key input unit 16 is pressed (S3), it is checkedwhether "3" is a key input signal (S4) and "3" is displayed on thedisplay 9 as an answer (S5). When a confirmation or acknowledge buttonof the key input unit 16 is next depressed (S6), the data indicative of"3" is stored in the memory 15 through the controller 8 (S7) and thecontroller 8 returns to the input standby state S1.

After the elapse of a predetermined time (i.e., after a time required torestrict the answer to the quiz has elapsed), a broadcasting stationsends a print instruction signal (write instruction signal) (S8). Whenthe print instruction signal is taken out from the data signal in themultibroadcasting wave through the extractor 7 in the input standbystate S1 (S9), it is checked whether the record of the answer stored inthe state S7 exists (S10). If the answer is found exist at S10, thenrandom-number data "1" sent subsequently to the print instruction signalfrom the broadcasting station is added to the data indicative of "3"taken out from the memory 15 (S11 and S12). As shown in FIGS. 3 and 4,the character information sent subsequently to the random-number datafrom the broadcasting station and the caller code 19 indicative "4" areprinted onto the card 17 (S13). When the above printing is finished, thecontroller 8 is brought into the input standby state (S1) again and theabove operation is similarly repeated in unison with the progress of thebroadcasting program.

Thereafter, the broadcasting station may send a read instruction signalto the reader 13 (before the completion of a program or during otherprogram after the completion of the program or during the sa week latera broadcasted a week later according to the contents of a quiz or thelike) (S14). When the read instruction signal is received through theextractor 7 (S15), the controller 8 controls the reader 13 to read "4"of the caller code 19 printed on the card 17 (S16). The controller 8receives a check or collation data signal indicating "4" (i.e., acorrect answer) sent after the read instruction signal from thebroadcasting station therein (S17) and checks it against the caller code19 read at S16 (S18). The result of check is printed on the lowest stageof the recording space on the card 17 in the form of characters and apredetermined caller code 20 (S19), then the routine procedure isfinished. Incidentally, the characters and the caller code 20 indicatingthe result of check (correctness or incorrectness relative to theanswer) may be variously stored and suitably outputted by referring tothe conversion table. Alternatively, they may be taken out from a datasignal carried by an additive-information radio wave and then printed asnecessary.

Thereafter, the audience brings the card 17 to card recovery locationsscattered within a broadcasting area. Further, the audience allows asuitable reader disposed at each card recovery location to read thecaller code 20 or presents characters indicative of the correctness orincorrectness relative to the answer to an employee, whereby theaudience accepts physical services such as gifts, benefits, merchandisecoupons, tickets, etc.

The second embodiment shows, as an example, the case where after theanswer (S3) has been issued from the key input unit 16, the check datasignal indicative of the correct answer is sent (S17). However, thefollowing procedure may be also considered. Namely, a check data signalis transmitted and stored in the memory M simultaneously with thesetting of the quiz (S2). Further, a count-down start signal is sent tocount the time that elapsed from the setting of a problem, on themultibroadcast receiver 1 side. After the elapse of a predetermined timeinterval, the answer given from the key input unit 16 is automaticallychecked against the check data stored in the memory M and the result ofcheck is printed on the card 17. This can prevent such accidents thatthe state of a radio wave becomes worse after the setting of a quiz sothat a print instruction signal cannot be received. Therefore such aproblem as, "Although the quiz has been set, the time required torestrict the reception of an answer cannot be reliably set off" will beeliminated.

Even if the broadcasting station does not actively transmit the printinstruction signal and the read instruction signal as in the secondembodiment, the audience can check the answer to the quiz program, whichis inputted by the use of the external inputting means 16, and canrecord the result of check on the card 17.

Briefly described, namely, the card 17 having the identification codefor the quiz program is inserted into the insert portion 12 of themultibroadcast receiver 1 to thereby bring the controller 8 into theexternal input reception mode. The broadcasting station sends theidentification code for the quiz program as header information andtransmits it inclusive of the data indicative of the correct answer tothe quiz within the general-purpose data area, which is sentsubsequently to the header. The extractor 7 takes out the identificationcode related to the contents of the broadcasting program from the headerinformation of the data signal in the multi-broadcasting radio wave, andsends the code to the controller 8. The controller 8 checks theidentification code taken out from the extractor 7 against theidentification code stored in the memory M. When they coincide with eachother, the controller 8 receives therein the data indicating the correctanswer within the general-purpose data area sent subsequently to theheader through the extractor 7 and checks the data against the datainputted from the key input unit 16. Finally, the result of check isprinted onto the recording spaces on the card 17 through the print unit10.

INDUSTRIAL APPLICABILITY

With the use of a multibroadcast receiver and a multibroadcast receivingsystem according to the present invention, as has been described above,a program and the contents of the program can be automatically selectedbased on an identification code recorded on a card so that necessaryinformation can be recorded on the card. Therefore, the labor ofselecting information can be saved and audio-visualized information canbe easily stored. Further, the program can be broadcasted under thesubstantial limitations to an audience by distributing cards fit for thepurpose of the broadcasting station side to the audience in advance. Therecording of the information on the card can be utilized not only as anaudiovisual certification for a broadcasting program but also as astatistical process such as an audience rating, a preference research ofan audience, or the like. Since the audience can answer to a quiz or aquestionnaire or the like by using an external inputting means, a moreinteresting program can be provided. Thus, both the audience side andthe broadcasting station side can more effectively utilize the radiomass media.
